Title: Generating circuit of digital color signal
Inventor: SUZUKI AKIRA
IPC: H04N17/02
Filed: 1980-03-18
Abstract: PURPOSE:To generate a digital chroma signal with a simple logic circuit by storing the half-period of a carrier chromaticity signal to ROM, and by adding the polarity code according to a sampling signal to the ROM output signal. CONSTITUTION:A chroma signal controlling a hue and chroma saturation from chroma control variable resistor VR1 is converted by A/D converter (a) into a signal which can select the chroma signal, and this signal is used as an address to store ROMd with a chroma level. Further, a sampling clock four times as large as a chrominance subcarrier wave from clock input terminal (b) is counted by counter (c) to output a polarity code signal for every one clock or every two clocks. Then, the chroma level stored in ROMd is applied to adding-subtracting circuit (f) together with the added polarity code signal and at the same time, a luminance signal digitized by A/D converter (e) is applied to circuit (f), which finds the sum or subtraction of both the luminance signal and the chroma level of the digital chroma signal. Then, they are processed by blanking gate circuit (g) to output a digital color signal.

Filed: 1982-03-08
Abstract: PURPOSE:To improve the indistinctness of a picture with regard to the target of an  infrared image pickup tube that displays the temperature distribution of a body in a  two-dimensional picture. CONSTITUTION:Belt-type grooves 14 are formed on one surface of a pyroelectric material 12 almost perpendicularly to the direction 16 in which the thermal diffusion coefficient is large. An electrode 13 comprises thinned conductive films made of gold,  aluminum, or nichrome so that almost all the incident infrared rays 4 may pass through them. For the material with small optical absorption factor in the infrared region, the  structure of the electrode 13 is composed of an infrared absorption layer used additionally as an electrode, for example, infrared absorption material such as gold black,  or bismuth black. The incident infrared rays 4 radiated from an object are absorbed  by a target 11 and temperature change distribution is induced in the pyroelectric  material 12 depending upon the distribution of the incident infrared rays 4. This temperature change distribution is read externally by an electron beam 5, but in this while  thermal diffusion occurs in the pyroelectric material 12. The thermal diffusion in the  direction with the large thermal diffusion coefficient is almost suppressed to zero by  the disconnecting function of the grooves 14 and the spatial resolution in this direction and the indistinctness of a picture can be improved.
